Disposer Jams No, these are not recipes for marmalade. This is where you can learn how to fix your food waste disposer if it gets jammed. Like when you lose a dish rag down the disposer, or when you try to grind up a piece of your silverware, or even when you just shoved too much food waste in it at once (see Do's and Don'ts.) But don't worry, we've all done these things a few times.
